Mac OS X Host
This section show how to install an operating system to your DragonBoard™ 410c using the SD Card method on a Mac OS X host computer. ***
- Step 1: Prepare MicroSD card
- Step 2: Find SD Card Device name
- Step 3: Recall Download Location
- Step 4: Unzip SD Card Install Image
- Step 5: Go to directory with SD Card Install Image folder using Terminal
- Step 6: Locate SD Card Install Image
- Step 7: Install Image onto SD Card
- Step 8: Prepare DragonBoard™ 410c with SD card
- Step 9: Install image onto DragonBoard™ 410c
Step 1: Prepare MicroSD card
- Ensure data from microSD card is backed up
- Note: Everything on microSD card will be lost by the end of this procedure.
Step 2: Find SD Card Device name
- You may need a MicroSD card adapter if your host computer only has an SD card slot
- On the host computer, open “Terminal” application (Press Command+Space bar and type “Terminal”)
- Remove SD card from host computer and run the following command:
- Note all recognized disk names (example: /dev/disk1)
- Insert SD card and run the following command (again):
- Note the newly recognized disk. This will be your SD card.
- Remember your SD card device name, it will be needed in Step 7.
Step 3: Recall Download Location
- Locate SD card install file that you got from Downloads page.
- This file will be needed for the next step.
Step 4: Unzip SD Card Install Image
- Uncompress or unzip the SD Card Install Image . With Mac OS X, you can use the Finder app to locate the file and then double click to automatically unzip the file.
- When unzipped, a folder (ex: dragonboard410c_sdcard_install_debian-83) will be created with the following contents:
- An install Image (.img) (ex: db410c_sd_install_debian.img)
- Readme or license.txt
Step 5: Go to directory with SD Card Install Image folder using Terminal
- On the host computer, open the “Terminal” application (Press Command+Space bar and type “Terminal”)
cdto the directory with your unzipped SD Card Install Image
cd <extraction directory> #Example: #<extraction directory> = /Users/YourUserName/Downloads #For this example we assume the "SD Card Install Image" is in the Downloads folder. cd /Users/YourUserName/Downloads
Step 6: Locate SD Card Install Image
- Make sure you are in the extraction directory
Unzipped SD Card download will be a folder. This folder should be found in your directory. Type
ls from command line for a list of files that can be found in your current directory:
ls #output dragonboard410c_sdcard_install_Y-XX
- Unzipped folder should be called dragonboard410c_sdcard_install_Y-XX, where Y can be Android or Debian and XX represents the release number
cdinto this directory
- Inside this folder you will find the install image where Y is Android or Debian.
.imgfile is what will be flashed or copied to your SD Card.
Step 7: Flash Image onto SD Card
- SD card inserted into host computer
- Recall SD Card device name from Step 2
- From within the dragonboard410c_sdcard_install_Y-XX folder, using the Terminal execute the following commands:
$ sudo dd if=db410c_sd_install_Y.img of=/dev/XXX bs=4m $ sudo sync
if=db410c_sd_install_Y.img: should match the name of the image that was downloaded.
of=/dev/XXX: XXX should match the name of the SD Card device name from Step 2. Be sure to use the device name without the partition name. For example, ‘of=/dev/disk1’
- If you get an error message “Resource Busy”, you will need to unmount the SD card without removing it from the host computer.
- Option 1:
- In the Applications folder, find and click on the Utilities folder.
- Click on the Disk Utility program to run it
- Select the device that represents the SD card
- Click on
unmountand leave the SD card in the computer
- Retry the ‘$ sudo dd if=db410c_sd_install_Y.img of=/dev/XXX bs=4m’
- Option 2:
- In the terminal window, enter this command:
$ sudo umount /dev/<device name>
- This command will take some time to execute. Be patient and avoid tampering with the terminal until process has ended.
- Once SD card is done flashing, remove from host computer and set aside for Step 8 You may see a popup window that tells you the device is Not readable by the operating system. Ignore the message and remove the MicroSD card from the host computer.
Step 8: Prepare DragonBoard 410c with SD card
- Make sure DragonBoard™ 410c is unplugged from power
- Set S6 switch on DragonBoard™ 410c to
0-1-0-0, “SD Boot switch” should be set to “ON”.
- Please see “1.1 Board Overview” on page 7 from DragonBoard™ 410c Hardware Manual if you cannot find S6
- Connect an HDMI monitor to the DragonBoard™ 410c with an HDMI cable, and power on the monitor
- Plug a USB keyboard and/or mouse into either of the two USB connectors on the DragonBoard™ 410c
- Insert the microSD card into the DragonBoard™ 410c
- Plug power adaptor into DragonBoard™ 410c, wait for board to boot up.
Step 9: Install image onto DragonBoard 410c
- If Steps 1 - 8 were followed correctly, the above screen should be visible from your DragonBoard™ 410c
- Select the image to install and click “Install” (or type “i”). OS will be installed into the eMMC memory
- This process can take a few minutes to complete
- Upon completion, “Flashing has completed and OS has installed successfully….” message will appear.
Before clicking “OK”:
- Remove the SD Card
- Set S6 switch on DragonBoard™ 410c to
0-0-0-0, all switches should be set to “OFF”
- Now click “OK” button and allow DragonBoard™ 410c to reboot.
Congratulations! You are now booting your newly installed operating system directly from eMMC on the DragonBoard™ 410c!
